As I said earlier, TYPE_ATTRIBUTES is NULL here anyway, because the
attributes hang in DECL_ATTRIBUTES of TYPE_DECL. And, except for
config/sol2.c (which looks wrong), nothing ever calls lookup_attribute for
"aligned" anyway, the user aligned stuff is encoded in TYPE_USER_ALIGN
and/or DECL_USER_ALIGN and TYPE_ALIGN/DECL_ALIGN.
